Analytical Functions in oracle explained with real examples
This video explains analytical functions and how they are implemented in real projects.
Analytical functions are somewhat similar to aggregate functions,but they offer much more.
Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times
They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function.
I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions.
You can find the sample problems along with dataset in the below link.
